编辑同志: 《电子学报》一九七九年第三期发表了本人的文章“背脊波导锁式铁氧体移相器的实验研究”。近两年来,随着研究工作的深入,发现对该文的式(17)进行适当的修正后,理论和实验更为吻合。实验发现:当h/b≈0.5时,不连续电容将使器件的差相移下降,考虑到不连续电容与h/b的固有关系,因此,对这种结构的移相器分两个区域予以补充和修正。 Editorial comrades: “Journals” in the third issue of 1979 published my article “experimental study of the ridge waveguide lock ferrite phase shifter.” In the recent two years, with the deepening of the research work, we found that theory and experiment are more consistent with the correct revision of equation (17). The experimental results show that when h / b≈0.5, the discontinuous capacitance will decrease the differential phase shift of the device. Considering the intrinsic relationship between the discontinuous capacitance and h / b, the phase shifter of this structure is divided into two regions Be added and amended.
